Chapter 3 Replace Hardware

Inspect, Clean, and Replace the Reusable Air Filter

Step 1 Move any cables that are routed in front of the fan-tray assembly and air filter so you can easily slide the filter out, as shown in Figure 3-3 on page 3-4.

Step 2 Grasp the metal tab at the edge of the filter and slide the filter out of the bracket while being careful not to dislodge any dust that may have collected on the filter.

Step 3 Visually inspect the filter material for dirt and dust.

Step 4 If the reusable air filter contains a concentration of dirt and dust, vacuum or wash the air filter. Prior to washing the air filter, replace the dirty air filter with a spare clean air filter (spare filters should be kept in stock).

Step 5 Wash the dirty air filter under a faucet with a light detergent. After washing the air filter, allow it to completely air dry for at least eight hours before reusing.

Note Cleaning should take place outside the operating environment to avoid releasing dirt and dust near the equipment.

Warning Do not put a damp filter back in the ONS 15327.

Step 6 Slide the clean air filter back into the shelf. (See Figure 3-4 on page 3-5.)
